Sucking him off until he bursts in my mouth

She fishes my cock out and sinks it all the way into her throat and I throw my head back. “Where’s mom?”
“She’s up in her room, got back from work an hour ago.”
I nod and head up stairs. Eporner “Fuck I’m gonna cum!”
She bites her lip and groans as I begin spurting rope after rope into her tight hole, her pussy milking my cock. “Yo, sis. I feel my body begin to tense and then I dump my load into her ass as she cums, almost shouting, biting her lip. While she’s doing this her hand is working up and down my shaft, until she lets go and sinks the rest of my cock into her mouth, her tongue whipping the underside of the entire length of my cock. I groan loudly, feeling myself getting closer. Shit… It won’t let you. “Uh Yeah, are you Lilith?”
She snorts a little and laughs, turning a little pink.
